本文提出了一种考虑铁损影响的异步电动机高效率、高响应的无速度传感器矢量控制方法，并讨论了系统的性能。所提出的矢量控制系统由考虑铁损的速度自适应转子磁链观测器组成，并采用直接磁场定向控制方案来补偿铁损的影响。仿真和实验结果表明，即使转子磁链发生变化，该系统也能估计电机速度。
This paper proposes a speed-sensorless vector control method for an induction motor operating at high efficiency and high response, in which core loss is taken into account, and discusses the system's performance. The proposed vector control system consists of a speed-adaptive rotor-flux observer which takes core loss into account and employs a direct-field-oriented control scheme which compensates for the influence of core loss. On the basis of simulation and experimental results, we show that the proposed system can estimate motor speed even when the rotor flux is changed.
